The bug I reported for debian (etch/lenny) also exists under debian
hardy.
see : http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=513596
It is not possible to "suicide" a luks encrypted disk, however it is a
"feature" (there is a warning message before doing that)
This is the output that explains the problem :
r...@computer:~# cryptsetup luksFormat /dev/loop0 key0.bin
WARNING!
========
This will overwrite data on /dev/loop0 irrevocably.
Are you sure? (Type uppercase yes): YES
Command successful.
r...@computer:~# cryptsetup luksAddKey --key-file key0.bin /dev/loop0 key1.bin
key slot 0 unlocked.
Command successful.
r...@computer:~# cryptsetup luksDelKey --key-file key0.bin /dev/loop0 0
key slot 0 unlocked.
No remaining key available with this passphrase.
Command failed.
r...@computer:~# cryptsetup luksDelKey --key-file key0.bin /dev/loop0 1

r...@computer:~# cryptsetup luksDelKey --key-file key0.bin /dev/loop0 0
